Key Features
- Fixed 1.2 V output with tight ±0.5% accuracy across load and temperature
- Ultra-low dropout voltage of 200 mV typical at 300 mA enabling operation from near-depleted batteries
- Active-low shutdown pin (SHDN) for system-level power sequencing and standby current reduction
- Wide input voltage range of 2.1 V to 6 V supporting single-cell Li-ion and dual-cell alkaline sources
- Tiny SOT-23-5 package minimizing PCB footprint in portable and wearable designs
Applications
The MCP1824T-1202E/OT is used in battery-powered portable devices such as wireless sensors, wearables, and IoT nodes where a stable 1.2 V rail is required with minimal PCB area. Its low 200 mV dropout voltage makes it ideal for single-cell LiPo systems that must operate at the end of the battery discharge curve. The SHDN pin enables efficient power gating in multi-rail embedded systems where subsystems are powered down to extend battery life.

Frequently Asked Questions
How does the 200 mV dropout voltage of the MCP1824T-1202E/OT benefit single-cell Li-ion battery designs?
With only 200 mV typical dropout, the MCP1824T-1202E/OT can maintain its 1.2 V regulated output when the Li-ion cell drops to approximately 1.4 V, significantly extending usable battery run time compared to regulators with 500 mV or higher dropout voltages. The maximum input is 6 V and minimum is 2.1 V.
What load current can the MCP1824T-1202E/OT supply, and does it require output capacitors?
The device supplies up to 300 mA continuous output current at 1.2 V. A small output bypass capacitor of at least 1 µF is recommended for loop stability. The 5-pin SOT-23 package keeps the external component count low, making it suitable for compact PCB layouts in handheld electronics.
How does the SHDN pin on the MCP1824T-1202E/OT support power management in multi-supply systems?
The active-low SHDN pin turns off the regulator output when driven low, reducing quiescent current to less than 1 µA. This allows the host microcontroller to gate power to peripherals, achieve deep standby states, and control power-up sequencing on boards where the 1.2 V rail must be enabled only during active processing.
In what compact board form factors is the MCP1824T-1202E/OT available, and how does package size compare to similar LDOs?
The MCP1824T-1202E/OT is supplied in a SOT-23-5 package measuring approximately 1.6 mm x 2.9 mm, one of the smallest through-able surface-mount packages for 300 mA LDO regulators. This makes it directly interchangeable with many 5-pin SOT-23 LDOs and suitable for high-density wearable and IoT PCB designs.
